Role of mitochonodrial genome in myocardial ischemia-reperfusion injury of spontaneously hypertensive rats (SHR) adapted to hypoxia.
 Brabcová, Iveta ; Žurmanová, Jitka (advisor) ; Mlejnek, Petr (referee)
Diplomová práce Abstract - Iveta Brabcová Abstract Ischemia-reperfusion heart injury is one of the most significant diseases affecting mankind and therefore current research pays more attention to its prevention and knowledge of the possible mechanisms which protect the heart. Adaptation to hypoxia has been known for several decades as a cardioprotective intervention but the main issues of protective mechanisms which are induced by the adaptation are still not completely understood. An important role of mitochondria as the main producers of energy and reactive oxygen species which can play a signalizing role in these mechanisms is confirmed in many studies. For this reason a special conplastic strain SHR/OlaIpcv-mtBN/Crl was created. This strain carries the nuclear genome of spontaneously hypertensive rat (SHR) and the mitochondrial genome of normotensive, highly resistant strain Brown Norway (BN). The aim of this study was to compare the expression of selected gene transcripts in the area of energy metabolism, of genes which are related to mitochondrial biogenesis and signaling and antioxidant systems. Comparing the expression was analyzed between strains and after chronic hypoxia adaptation, which cause cardioprotective phenotype in both of these strains. Our results showed a different expression HIF-1α...
